Maybe it's just me

, but I've noticed in recent years (maybe 7 at the most) that the word "
as" is more and more being used in substitution of the word "
because". I am wondering, after hearing "
as" used in this manner for some time now, if it is really a correct way to use it. I've noticed that this way of using "
as" has caught on and is in common usage, especially in today's writing. I most often come across this in formal writing and its verbal usage seems to be catching on.

For instance:
"How do I move on,
as everything seems to get in the way?"
...in comparison to:
"How do I move on,
because everything seems to get in the way?"
